Answer:
It should be B -An unknown mtDNA sample is matched to a sample of mtDNA that was found at a crime scene
Explanation:
I took the test and it came back right for me
Mitochondria are organelles that have their own (non-nuclear) genetic material (DNA). In forensic science, an unknown mtDNA sample is matched to a sample of mtDNA that was found at a crime scene.
The sequential order of nucleotides in the DNA mitochondrial sequence (i.e., mtDNA) can be used to identify individuals by comparing mtDNA sequences of different samples.Mitochondria are only inherited from the mother, thereby mtDNA exhibits a matrilineal inheritance pattern.In conclusion, in forensic science, an unknown mtDNA sample is matched to a sample of mtDNA that was found at a crime scene.Learn more in:

A student is measuring the lengths of caterpillars for an experiment. She measures 100 caterpillars using a ruler that measures to the nearest centimeter. Which statement describes a change that could help improve the results of her experiment? O A. Her measurements will be more precise if she measures an additional 100 caterpillars. O B. Her measurements will be more accurate if she measures an additional 100 caterpillars. O C. Her measurements will be more accurate if she uses a ruler that measures to the nearest millimeter. O D. Her measurements will be more precise if she uses a ruler that measures to the nearest millimeter Please help
Answer:
B and C
Explanation:
The student's measurement would be more accurate if she can measure an additional 100 caterpillars and be more precise if she uses a ruler that measures to the nearest millimeter.
Accuracy refers to the closeness of measurement or group of measurements to the true value while precision is the closeness of repeated measurements.
The accuracy of a measurement is increased by increasing the number of sample measurements. The more the sample measurements, the lesser the deviation of the mean from the true value.
The precision of a measurement is increased by being able to measure small differences. Hence, a ruler that measures to the nearest millimeter would be more precise than a ruler that can only measure in centimeter.
The correct option is B and C.

Hummingbird wings require a tremendous amount of energy to flap their wings so fast. Therefore, ___________ organelles might be very abundant in the wing muscles of a hummingbird.
Answer:
The cell organelle, Mitochondria will be very abundant in the wing muscles of a hummingbird.
Explanation:
Mitochondria are known as the powerhouses of the cell. They are are membrane-bound organelles which are found within the cytoplasm of the cells. They are the site for cellular respiration in the cell. The take in nutrients and breaks them down to produce energy in the form of ATP.
Actively respiring tissues and organs possess an abundance of mitochondria which produces the energy required by these tissues and organs.
Since hummingbirds require a tremendous amount of energy to flap their wings so fast, therefore, mitochondria would be very abundant in the wing muscles of a hummingbird.

Why does cell division remain important to an adult organism even after it is fully developed?
Answer:
Cell division prevents cancers, and is something that in humans and in other adult organisms as well prevents old age.
There are many more complex mechanisms that contribute to old age and cancers, but if cell division slows down an organism reaches the end of its life.
Every set of cells has a limited amount of divisions it can do. literally every organism from the moment of conception is dying.

Life can exist under frozen surfaces in polar seas because…
Answer:
Life exit under frozen surfaces in polar seas because of the anomalous behavior of water.
Explanation:
Water behaves irregularly, which helps in preventing the total freezing of seas during winter.
Since water has its highest density at [tex]4^{o}[/tex]C, the surface of seas freezes while the lower regions or layers is in form of liquid. During winter, as the temperature decreases to [tex]4^{o}[/tex]C, the layer of water with highest density sinks to the bottom while those that are less dense floats to the top. Thus when the surface temperature is below [tex]0^{o}[/tex], the lower layers under the frozen surface are at temperature range between [tex]1^{o}[/tex]C to [tex]4^{o}[/tex]C
